The LensCheck Small Format Finite Conjugate System is configured for measuring MTF and other properties of lenses designed for close conjugate imaging. This compact system allows measurements at object distances from 0 to 300mm, over field diagonals up to 250 mm. It’s available as a stand-alone system, or as an accessory to the standard LensCheck VIS system used for infinite conjugate measurements.
Ideal for measuring finite conjugate lenses in applications that include:
- Medical imaging and surgical applications
- Cell imaging systems
- Low-magnification microscopy
- Finite conjugate objectives (objective/tube lens pairs)
- Inspection or short-TTL machine vision optics
- Macro lenses
